An intelligent ventilation system for indoor buildings

Abstract

The present invention discloses an intelligent ventilation system for indoor buildings applied to the field of ventilation. The system monitors the wind speed and direction in real time by adding a wind speed and direction sensor on the basis of an existing intelligent fan, thereby controlling two adaptive wind hoods to face the directions of headwind and downwind respectively, so that the wind can be used to assist the supply and exhaust of air, thereby effectively saving energy consumption.

In addition, the wind receiving seat is moved to open a channel connecting the outside world with the inside of the self-cleaning filter box, so that the wind can be directly blown into the inside of the self-cleaning filter box for self-cleaning, thereby further effectively improving the dust filtering effect, reducing the burden of rear-end air purification, achieving the supply and exhaust of air with the help of wind force, effectively saving energy consumption, and being able to adapt to changes in wind speed and effectively improving the dust filtering effect.

Description

Technical Field

[0001] The invention relates to the field of ventilation, and in particular to an intelligent ventilation system for indoor buildings. Background Art

[0002] The intelligent ventilation system can integrate relevant equipment and components into a system according to the building's functions and design requirements, and realize local and remote intelligent control and management, which not only meets the building's indoor ventilation function requirements and ensures ventilation safety, but also saves energy and reduces consumption.

[0003] Existing indoor intelligent ventilation systems rely on external fans to complete air supply and exhaust, so fans are an important part of indoor ventilation systems. Most existing fans are intelligently controlled. Although they can automatically adjust the air supply and exhaust volume, the energy consumption of intelligent fans is also high, and they cannot make good use of wind energy to achieve energy conservation and emission reduction. In addition, the dust filtration effect of existing fans in the air supply stage is also poor, which adds a burden to air purification.

[0004] To this end, we use this technical solution to solve the problems of high energy consumption and poor dust filtration effect of existing intelligent ventilation systems. Summary of the invention

[0005] The purpose of the present invention is to improve the intelligent ventilation system in the prior art. Compared with the prior art, an intelligent ventilation system for indoor buildings is provided. Wind speed and direction sensors are added to the existing intelligent fans to monitor wind speed and direction in real time, so as to control two adaptive wind hoods to face the directions of headwind and downwind respectively. In this way, wind force can be used to assist air supply and exhaust, thereby effectively saving energy consumption. The wind receiving seat receives the action of wind force, so that the moving wind plate and the fixed wind plate are dislocated and moved. In strong wind weather, the air supply speed can be effectively slowed down to avoid damage to the fan caused by sand and dust carried in the wind, and the dust filtering effect of the self-cleaning filter box can be effectively improved. In addition, the channel connecting the outside world and the inside of the self-cleaning filter box is opened by moving the wind receiving seat, so that wind can be directly blown into the inside of the self-cleaning filter box for self-cleaning, thereby further effectively improving the dust filtering effect and reducing the burden of rear-end air purification.

[0006] It can realize air supply and exhaust with the help of wind power, effectively save energy, adapt to changes in wind speed, and effectively improve dust filtering effect.

[0007] Furthermore, a driving gear meshing with the gear ring is fixedly connected to the output end of the servo motor, and the servo motor drives the gear ring to rotate at an angle of 0-90° each time. When the gear ring rotates too much in one rotation, the two hoses will be entangled with each other, thereby causing rupture and damage to the hoses. Therefore, in order to prevent the two hoses from being entangled, the servo motor is used to ensure that the gear ring rotates at a angle of no more than 90° each time.

[0008] Furthermore, each group of two adaptive wind hoods are always distributed back to back, and the two adaptive wind hoods face the upwind and downwind directions respectively. The adaptive wind hoods used for supplying air face against the direction of the wind, and the adaptive wind hoods used for exhausting air face along the direction of the wind. In this way, air supply and exhaust can be achieved with the help of wind power, thereby effectively saving energy consumption and realizing the utilization of natural resources.

[0009] Furthermore, the fixed air plate and the moving air plate are provided with grille openings of the same number and shape, and the height of the moving air plate is greater than that of the fixed air plate. The grille openings on the fixed air plate and the moving air plate play a role in ventilation. When the moving air plate is pushed by the wind seat in strong wind weather, the moving air plate and the fixed air plate are dislocated and moved, thereby effectively reducing the wind speed, and at the same time effectively improving the dust filtering effect of the self-cleaning filter box.

[0010] Optionally, air ducts are provided on the upper and lower sides of the partition seat located at the wind receiving seat, and the self-cleaning filter box is connected to the air duct, a groove is provided on the inner wall of the air duct close to the telescopic cavity, and a magnetic sealing plate is slidably connected in the groove and is in sealing contact with the inner wall of the air duct, a wavy elastic wire is also fixedly connected between the magnetic sealing plate and the groove, and a permanent magnet block that is magnetically attracted to the magnetic sealing plate is fixedly embedded in the side wall of the wind receiving seat. In strong wind weather, the wind receiving seat moves inward after being blown by the wind, and when the permanent magnet block on the wind receiving seat is close to the bottom of the magnetic sealing plate, the magnetic attraction causes the magnetic sealing plate to retract into the groove. At this time, the air duct is connected with the external environment, so that wind energy can directly blow into the interior of the self-cleaning filter box, so as to blow dust on both sides of the self-cleaning filter box to achieve self-cleaning, thereby effectively improving the dust filtering effect of the self-cleaning filter box.

[0011] Optionally, the self-cleaning filter box includes dust filters on both sides, and the upper and lower ends of the two dust filters are fixedly connected with edge seals, a bellows connected to the air duct is fixedly embedded between the two dust filters, and the upper side wall of the bellows is connected with a plurality of equally spaced air columns, and the air columns are provided with a plurality of air jets on the side walls of the dust filters on both sides. After the wind is blown into the bellows, the airflow is blown from the air jets on the air columns to the filters on both sides, so as to blow off dust, flying catkins and other impurities accumulated on the self-cleaning filter box, thereby realizing self-cleaning of the self-cleaning filter box, effectively improving the dust filtering effect of the self-cleaning filter box, and eliminating the trouble of disassembly and cleaning.

[0012] Optionally, the dust filter includes a filter screen, and a solid body is fixedly connected to the upper and lower ends of the filter screen. The height of the filter screen is equal to the height of the wind plate. The dust filtering effect of the self-cleaning filter box is effectively improved by the front and rear filters. In this way, the sand, dust and flying catkins carried in the wind in strong wind weather can be well filtered out, thereby effectively reducing the burden of rear-end air purification.

[0013] Furthermore, the reset member includes two symmetrically distributed hyperbolic elastic sleeves, and an elastic net is filled between the two hyperbolic elastic sleeves. The elastic net relies on its own elastic force to reset the moving air plate, and the elastic net below relies on part of its own elastic force to offset the weight of the moving air plate, so that the moving air plate and the fixed air plate remain parallel.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] (1) By adding wind speed and direction sensors to the existing intelligent fan to monitor the wind speed and direction in real time, the two adaptive wind hoods are controlled to face the headwind and the downwind directions respectively, so that the wind can be used to assist the air supply and exhaust, thereby effectively saving energy consumption. The wind receiving seat receives the wind force, so that the moving wind plate and the fixed wind plate are dislocated and moved, which can effectively reduce the air supply speed in strong wind weather, avoid the sand and dust carried in the wind from causing damage to the fan, and effectively improve the dust filtering effect of the self-cleaning filter box. In addition, the wind receiving seat is moved to open the channel connecting the outside world with the inside of the self-cleaning filter box, so that the wind can directly blow into the inside of the self-cleaning filter box for self-cleaning, thereby further effectively improving the dust filtering effect, reducing the burden of rear-end air purification, and realizing the air supply and exhaust with the help of wind, effectively saving energy consumption, and being able to adapt to changes in wind speed, and effectively improving the dust filtering effect.

[0016] (2) A driving gear meshing with the gear ring is fixedly connected to the output end of the servo motor, and the servo motor drives the gear ring to rotate at an angle of 0-90° each time. When the gear ring rotates too much in one rotation, the two hoses will be entangled with each other, causing the hoses to rupture and be damaged. Therefore, in order to prevent the two hoses from being entangled, the servo motor is used to make the gear ring rotate at an angle of no more than 90° each time.

[0017] (3) Each group of two adaptive hoods are always distributed in back-to-back directions, and the two adaptive hoods face upwind and downwind respectively. The adaptive hood used for air supply faces against the direction of the wind, and the adaptive hood used for exhaust faces along the direction of the wind. In this way, air supply and exhaust can be achieved with the help of wind power, thereby effectively saving energy consumption and realizing the utilization of natural resources.

[0018] (4) The fixed air plate and the moving air plate are provided with grille openings of the same number and shape, and the height of the moving air plate is greater than that of the fixed air plate. The grille openings on the fixed air plate and the moving air plate play a role in ventilation. When the moving air plate is pushed by the wind seat in strong wind weather, the moving air plate and the fixed air plate are displaced and moved, thereby effectively reducing the wind speed and effectively improving the dust filtering effect of the self-cleaning filter box.

[0019] (5) The partition seat is located on both sides of the wind receiving seat, and air ducts are provided on the upper and lower sides, and the self-cleaning filter box is connected to the air duct. A groove is provided on the inner wall of the air duct close to the telescopic cavity, and a magnetic sealing plate is slidably connected in the groove to seal the inner wall of the air duct. A wavy elastic wire is also fixedly connected between the magnetic sealing plate and the groove. A permanent magnet block that is magnetically attracted to the magnetic sealing plate is fixedly embedded in the side wall of the wind receiving seat. In strong wind weather, the wind receiving seat moves inward after being blown by the wind. When the permanent magnet block on the wind receiving seat is close to the bottom of the magnetic sealing plate, the magnetic attraction causes the magnetic sealing plate to retract into the groove. At this time, the air duct is connected to the external environment, so that wind energy can directly blow into the interior of the self-cleaning filter box, thereby blowing dust on both sides of the self-cleaning filter box to achieve self-cleaning, thereby effectively improving the dust filtering effect of the self-cleaning filter box.

[0020] (6) The self-cleaning filter box includes dust filter elements on both sides, and the upper and lower ends of the two dust filter elements are fixedly connected with edge seals. A bellows connected to the air duct is fixedly embedded between the two dust filter elements, and the upper side wall of the bellows is connected with a plurality of air columns distributed at equal intervals. The air columns are provided with a plurality of air jets on the side walls of the dust filter elements on both sides. After the wind is blown into the bellows, the airflow is blown from the air jets on the air columns to the filters on both sides, thereby blowing off the dust, flying catkins and other impurities accumulated on the self-cleaning filter box, thereby realizing self-cleaning of the self-cleaning filter box, effectively improving the dust filtering effect of the self-cleaning filter box, and eliminating the trouble of disassembly and cleaning.

[0021] (7) The dust filter includes a filter screen, and the upper and lower ends of the filter screen are fixedly connected with a solid body. The height of the filter screen is equal to the height of the fixed wind plate. The dust filtering effect of the self-cleaning filter box is effectively improved by the front and rear filters. In this way, the sand, dust and flying catkins carried by the wind in strong wind weather can be well filtered, thereby effectively reducing the burden of rear-end air purification.

[0022] (8) The reset member includes two symmetrically distributed hyperbolic elastic sleeves, and an elastic net is filled between the two hyperbolic elastic sleeves. The elastic net relies on its own elastic force to reset the moving wind plate, and the elastic net below relies on part of its own elastic force to offset the weight of the moving wind plate, so that the moving wind plate and the fixed wind plate remain parallel.

DETAILED DESCRIPTION

[0035] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present invention.

When the gear ring 6 rotates too much in one rotation, the two hoses 103 will be entangled with each other, thereby causing the hose 103 to be broken and damaged. Therefore, in order to prevent the two hoses 103 from being entangled, the servo motor 5 is used to make the gear ring 6 rotate at an angle of no more than 90° each time;

[0039] See also Figure 1 , 3 The intelligent fan body 1 includes a wind speed and direction monitoring module, a steering adjustment module, an air extraction adjustment module and an exhaust adjustment module.

The fixed wind plate 8 and the moving wind plate 9 are provided with the same number and shape of grilles, and the height of the moving wind plate 9 is greater than the height of the fixed wind plate 8. The grilles on the fixed wind plate 8 and the moving wind plate 9 play a ventilation role. When the moving wind plate 9 is pushed by the wind seat 11 in strong wind weather, the moving wind plate 9 and the fixed wind plate 8 are dislocated and moved, thereby effectively reducing the wind speed. At the same time, it can also effectively improve the dust filtering effect of the self-cleaning filter box 10, and the partition seat 7 is located between the moving wind plate 9 and the fixed wind plate 8. A self-cleaning filter box 10 is also inlaid at the position where the partition seat 7 is located between the moving wind plate 9 and the fixed wind plate 8;

The elastic net 1202 relies on its own elastic force to reset the moving air plate 9, and the elastic net 1202 below relies on part of its own elastic force to offset the weight of the moving air plate 9, so that the moving air plate 9 and the fixed air plate 8 remain parallel.

[0042] Embodiment 2:

[0043] Based on Example 1, please refer to Fig. 9, the partition seat 7 is located at the upper and lower sides of the wind receiving seat 11, and both sides of the wind duct 703 are provided with air ducts, and the self-cleaning filter box 10 is connected with the air duct 703. The air duct 703 is provided with a groove near the inner wall of the telescopic cavity 701, and a magnetic sealing plate 14 is slidably connected in the groove and is in sealing contact with the inner wall of the air duct 703. A wavy elastic wire 13 is also fixedly connected between the magnetic sealing plate 14 and the groove. The side wall of the wind receiving seat 11 is fixedly inlaid with a permanent magnet block 1102 that is magnetically attracted to the magnetic sealing plate 14. In strong wind weather, the wind receiving seat 11 moves inward after being blown by the wind. When the permanent magnet block 1102 on the wind receiving seat 11 is close to the bottom of the magnetic sealing plate 14, the magnetic attraction causes the magnetic sealing plate 14 to retract into the groove. At this time, the air duct 703 is connected with the external environment, so that wind energy can directly blow into the interior of the self-cleaning filter box 10, so as to blow dust on both sides of the self-cleaning filter box 10 to achieve self-cleaning, thereby effectively improving the dust filtering effect of the self-cleaning filter box 10;

[0044] See also Figure 6 The self-cleaning filter box 10 includes dust filter elements 1001 on both sides, and the dust filter element 1001 includes a filter screen 10011, and the upper and lower ends of the filter screen 10011 are fixedly connected with a solid body 10012, and the height of the filter screen 10011 is equal to the height of the fixed wind plate 8. The dust filtering effect of the self-cleaning filter box 10 is effectively improved by the front and rear two filter screens 10011, so that the sand and flying catkins carried by the wind in strong wind weather can be well filtered down, thereby effectively reducing the burden of rear-end air purification, and the upper and lower ends of the two dust filter elements 1001 are fixedly connected with a sealing edge 1003, and the two dust filter elements 10 01 is fixedly embedded with a bellows 1002 connected to the air duct 703, and the upper side wall of the bellows 1002 is connected with a plurality of air columns 1004 distributed at equal intervals. The air columns 1004 are provided with a plurality of air jets on the side walls of the dust filters 1001 on both sides. After the wind is blown into the bellows 1002, the airflow is blown from the air jets on the air columns 1004 to the filter screens 10011 on both sides, so that dust, flying catkins and other impurities accumulated on the self-cleaning filter box 10 are blown off, thereby realizing self-cleaning of the self-cleaning filter box 10, effectively improving the dust filtering effect of the self-cleaning filter box 10, and eliminating the trouble of disassembly and cleaning.

[0045] The working principle of this scheme is as follows: first, the wind speed and direction sensor 4 monitors the changes of wind speed and direction in real time, and the monitored data is transmitted to the wind speed and direction monitoring module for summary processing. When the wind speed and direction change, the wind speed and direction monitoring module sends a signal to the steering adjustment module. The steering adjustment module starts the servo motor 5 through the control processor to drive the gear ring 6 to rotate, so that the adaptive wind hood 3 of the air supply goes against the direction of the wind to achieve the use of wind. The wind speed and direction monitoring module sends signals to the exhaust adjustment module and the exhaust adjustment module at the same time, and adjusts the start and stop and speed of the supply and exhaust fans of the air supply fan 101 and the exhaust fan 102 in real time according to the monitored wind speed data, thereby effectively saving energy consumption. When encountering strong wind weather, the wind receiving seat 11 is affected by the wind After the blowing action, it moves inward. When the wind receiving seat 11 moves, the moving air plate 9 is pushed to both sides by the hydraulic action, so that the moving air plate 9 and the fixed air plate 8 are misaligned, thereby effectively slowing down the wind speed. In this way, the self-cleaning filter box 10 can effectively filter the mud, sand, flying catkins and other impurities carried in the wind when the air is supplied. When the wind receiving seat 11 moves, when the permanent magnet block 1102 is close to the bottom of the magnetic sealing plate 14, the magnetic attraction causes the magnetic sealing plate 14 to retract into the groove. At this time, the air duct 703 is connected with the external environment, so that the wind can be directly blown into the interior of the self-cleaning filter box 10, and the airflow is blown by the jet port on the air column 1004 to the filter screens 10011 on both sides to achieve self-cleaning, thereby effectively improving the dust filtering effect of the self-cleaning filter box 10.

[0046] The above description is only the best implementation mode adopted by the present invention in combination with current practical needs, but the protection scope of the present invention is not limited thereto.
